--2 Claims.

This invention relates to means for reconditioning the cutting edges ofrazor blades.

Broadly, it is an object of my invention to provide a means .forreconditioning the cutting edges of razor blades in combination or inassociation with a safety razor.

More particularly, it is an objectof my invention to provide a movableplate between the blade and the cap of a razor so that by moving theplate laterally, the edges of the plate will realign theirregularities"of the cutting edges.

During the shaving process, .the hairs bend parts of the fine cuttingedge outward so that the cutting edge loses its keenness Various meanshave been employed to sharpen the cutting edges,..such as honing on aflat or arcuate :stone, strapping, etc. I have .found that by moving astraight edge over the cutting edges .of the blade that theirregularities of the cutting edges created in shaving become easilystraightened thus realigning the cutting edges and prolonging theshaving life of the blade.

A further object is to provide a combination cap and reconditioningmeans for a safety razor blade.

For a fuller understanding of the nature and objects of the invention,reference is had to the following detailed description, in connectionwith the accompanying drawing, in which:

Figure 1 is a top view of a safety razor with part of the cap and partof the plate for realigning the cutting edges broken away, therealigning plate being shown in shaving position.

Figure 2 is a side view thereof, part of the handle being broken away.

Figure 3 is an enlarged side view, partly in section, showing therealigning plate moved over one cutting edge, the opposite cutting edgebeing shown partly bent upward after use.

Figure 4 is a view taken along line 44 of Figure 3 showing the onecutting edge having been realigned while the opposite cutting edge showsthe irregularities after shaving, part of the realigning plate beingshown partly broken away.

Figure 5 is a greatly enlarged view of one corner of the realigningplate and razor blade showing the edge of the plate over the cuttingedge of the blade, the corner of the plate having been broken away toshow the irregularities of the cutting edge of the blade after shaving.

Figure 6 is a top view of a modified form of the invention comprising acombination cap and slideable member for realigning the cutting edges ofa blade in shaving position, parts shown broken away.

'2 Figure 7 is the same view as Figure '6 except that the parts areshown in position for realigning the irregularities of the cutting edgesof the blade. I Figure 8 is a section taken through line 8--8 ofFig-ure7.

Referring to the drawing, numeral [0 represents a cap having a concaveinner surface 'H with a central projecting screw l2 well known in therazor art. An arcuate plate '13 of the same arc as the concave innersurface I I is posit'ioned beneath the cap 'I'D. ;'Plate 13 has acentral opening 14 and other openings 15 and a pair or opposedprojections or flanges it); the space between flanges ltbeing slightlywider than the length "of the cap Ill. The edges I! of cap H] act asguides for plate 13. The inner surfaces of theflanges ifislide againstedges I! of the cap fljD when theplate I3 is manually moved laterally.Central screw i2 passes through opening 114 and the openings l5 permitany depending parts, such astlugs-"(riotshowm 'to pass through openings[5. Thefedge's I53 and I9 act as stops against screw l2 to limit thelateral,movement of plate F3. The "edges of openings 15 maybe used 'forthe same pur ose, that is to act as stops against any projeotfons thebottom of the cap. The longitu'din'al-edges 20 of plate T3 are roundedand are 'p'erm'itt'ed'to slide over the cutting edges 2.! and 22 of theblade 23, since the size of opening it is large enough to permit edges223 to pass over cutting edges 2| and 22.

A flexible razor blade 23 is placed between the plate l3 and theplatform 25 as is well known in the art. Handle 25 is screwed onto screwl2 drawing the cap downward, flexing blade 23 and tightening the platel3 and blade 23 between the cap I0 and platform 24, preventing movementof the blade and plate l3.

In order to use the plate I3 for reconditioning the cutting edges of theblade 23, the handle 25 is turned so that the cap l 9 is loosenedsufliciently to permit the plate I3 to be moved laterally by the thumband one finger pressing upon the opposed flanges l6. The edges 28 ofplate 13 ride over the cutting edges 2| and 22 of the blade thusstraightening the irregularities created in the cutting edges byshaving.

When the plate [3 is in the center of the razor as shown in Figures 1and 2, and the handle 25 tightened, the razor is in condition forshaving.

Referrin to Figures 6, 7, and 8 which show a modification of the deviceshown in Figures 1 to 5 inclusive, numeral 26 is a movable plate with anarcuate inner surface 21 and having a rectangular opening 28 and a pairof opposed notches 29 communicating with opening 28. Projecting intoopening 28 at each end are opposed pins or lugs 30. A bar 31 iscentrally disposed within the rectangular opening 28 running parallelthereto. At each end of the bar 3| there is a notch 32 within which thepin 30 rides. A depending screw (not shown) projects from the center ofthe bar 3! and is adapted to pass through a central opening in theplatform 33. A handle similar to 25 is adapted to screw onto thedepending screw in order to tighten the bar 3|. A pin 34 projects fromthe center of the bar 3|. A slideable lockin member 35 having an opening36 into which pin 34 passes and having depending projections 39 isadapted to slide longitudinally upon bar 3i. Lugs 31 projecting from thelower portion of bar 3! are adapted to fit within channel 38 of platform33.

In order to use the device shown in Figures 6 to 8 inclusive, adouble-edged blade is placed upon the arcuate platform 33 and thecentral screw depending from the movable bar 3i passed through the wellknown channel of the blade 23. The handle is then screwed onto thedepending screw so that the blade 23 is flexed. The posi- The razor isnow in position and the slideable lockin member moved to the left asshown in Figure 7 so that the depending projections 39 are aligned withthe opposed notches 29. The edges 40-46 of the movable plate '26 arethen grasped between the fingers and moved laterally from side to sideso that the longitudinal edges 4! ride over the cutting edges 2| and 22of the blade thus straightening the irregularities of the cutting edgesdue to shaving. During the lateral movement of plate 26 pins 30 movewithin the notches 32 of the bar 3| and projections 39 enter the notches29. In order to again lock the razor in shaving position, plate 26 ismoved centrally over platform 33, the locking member 35 is moved to theright as shown in Figure 6 and the handle is then tightened.

It is obvious that various changes and modifications may be made in thedetails of construction and arrangement of parts without departing fromthe general spirit of the invention,
